In our 54th reading group meeting, we were looking for an answer to an important question in the distributed systems community: “What about Raft?” We looked at the “ Paxos vs Raft: Have we reached consensus on distributed consensus? ” paper to try to find the answer. As always, we had an excellent presentation, this…

Running IntelliJ IDEA with JDK 17 for Better Render Performance with Metal, by Mustafa Akın.
Research software (i.e., software written to support research in engineering or the sciences) is usually a tangled mess of spaghetti code that only the author knows how to use. Very occasionally I encounter well organized research software that can be used without having an email conversation with the author (who has…
Edit 2021-03-30: Jeremy Mikkola wrote about some closely related topics back in 2017. Edit 2021-03-31: Chris Siebenmann wrote a response to this post that explains exactly how interface values that are nil are typed. It’s more complicated than I thought! I’m not sure I have another Rust & Postgres blog post in me…
How the public healthcare system in Italy is using software to support the vaccination effort is appaling. I’ve spent a good part of the last 30 years trying to convince people that software is imp…

Schema migrations are tricky, especially when planned downtime is not an option. Changes need to be carefully designed to stay backwards compatible so that…
Programming language memory models answer the question of what behaviors parallel programs can rely on to share memory between their threads. For example, consider this program in a C-like language, where both x and done start out zeroed.
Mugo is a single-pass compiler for a tiny subset of the Go programming language -- just enough to compile itself.

I used to think that I didn’t need comments if I wrote self-documenting code. However, I have realized that I do write comments, and that I find them really useful. To see how many comments I…
I took the real app and convert it from Styled Components to Linaria to compare the app performance of CSS-in-JS and normal CSS. Continue reading if you want to know how it went.

Audio on Unix is a little zoo, there are so many acronyms for projects and APIs that it's easy to get lost. Let's tackle that issue! Most articles are confusing because they either use audio technical jargon, or because they barely scratch the surface and leave people clueless. A little knowledge can be dangerous.
Batching work is more efficient … until cost rises nonlinearly with batch size. Then smaller batches are the most efficient. So don’t delay maintenance!
Programming in logic can help you produce better optimized, more secure, bug-free code … if only you knew how to do it.
In one of my recent training courses, a student informed me that both clang-tidy and PVS-Studio were complaining about some code of the form

How I Write Code: Pen & Paper - Noteflakes
In August, I set out to improve the machine learning ecosystem for Ruby and wasn’t sure where it would go. Over the next 5 months, I ended up...
When I was a kid, I wrote a BASIC program to explore Conway’s Game of Life on my 8088. It was painfully slow, so I began an assembly rewrite. But I failed at Life: I abandoned the project in frustration because I kept freezing up my system.
